On Hold (Expired) means that the item went to the Hold shelf successfully, but was never picked up by the user. The "Expired" part is pulled out of WorldCat Discovery display to avoid having users coming to the desk forcing staff to pull items from other users.
If you have one of these titles and need it for other uses, you should be able to pull the item from the hold shelf and check it back in to clear the On Hold (Expired) status.
There is more on Item Statuses and clearing the Hold shelf.
